TYPEWRITING MACHINE Filed Sept. 26, 1927 2 ShQGCS-ShGBt 2 atented Aug. 11, 1931 CARL W. BRENN, 0F MONTCLAQIR, NEW JERSEY,'ASSIGNOR TO AUTGGRAPHIC REGISTER COMPANY, OF HOBOKEN, NEW JERSEY, A COMPANY OF NEW JERSEY TYPEWRITING MACHINE Application filed September 26, 1927. Serial No. 221,913.

This invention relates to typewriting machines, and more particularly to means for guiding and controlling a pile of continuous worksheets as they are led to the platen for writing operations from a supply pile located on the desk or on the floor.

An object of this invention is to provide for guiding a pile of worksheets so that free traveling movement of the carriage with relation to the non-traveling supply pile is permitted without damaging or producing undesirable effects on the worksheets, or without any perceptible drag being placed on the movements of the typewriter carriage.

Another object is to gradually bring the pile of worksheets to a predetermined point at the introductory side of the platen, andat the same time cause the individual sheets of the pile to be brought into registration with each other laterally.

Other objects and advantages will hereinafter appear. I

In the accompanying drawings which illustrate one form of the invention, that at present preferred Fig. 1 is a side view of a typewriting machine showing guiding means of the present invention in section.

Fig. 2 is a top plan view of the parts shown in Fig. 1. V

The typewriting machine shown in the accompanying drawings comprises a frame 10 aving a carriage 11 for supporting a platen 12 around which worksheets are fed when the platen is rotated as a result of the engage ment of feed rollers 13 with the worksheets. At the delivery side of the platen 12 there may be provided a guide roller 14 supported by a bail 15 as shown in the drawings, although other means for controlling the worksheets at the delivery side of the platen may e provided within the scope of this invention. The platen is moved step-by-step to linespace the worksheets which are supported upon it as is usual, and the carriage is moved laterally step-by-step in letter feed direction by any suitable means.

According to the resent invention, a pile 16 of worksheets 1 of indefinite lengths,

hereafter called continuous, is led from a packor other source of supply 18, supported at a point remote from the carriage on thefloor behind the typew-ritin machine 10, or on the desk supporting the latter, upwardly to a paper table 19 provided by the present invention. This paper table 19 is secured attable 19 extends upwardly and rearwardly over the rear end 23 of a typewriter carriage and the back 24 of the typewriting machine frame, and then downwardly toward the supply of paper 18 which, it Wlll be observed, is stationary relative to the traveling movements ofthe typewriter carriage. At its rearward and lower end 25, the paper table 19 extends outwardly, as seen in Fig. 2, and along its side edges is provided with walls 28. These walls 28 with the cover 26 constitute a chute 19a through the open mouth 29 of which the pile 16'of worksheets 17 passes. The pile of worksheets 16 passes out of this chute at its more restricted opening 30 and continues to lie on the curved table 19 as it is moved forwardly toward the end 22 where they enter the bight of the platen l2 and pressure roller 13.

When the typewriter carriage 12 is in a centralized position shown in Fig. 2, the pile 16 of worksheets will extend rearwardly in substantially a straight line and will thus be in a position shown at A in Fig. 2. However, when the carriage is moved to the right or, in other words, to the position it assumes at the beginning of a line, the part of the pile of worksheets on the platen moves to the right, but the stretch leading up from the pack or supply 18 does not so move and, consequently the part of the pile in the chute skews and take the position indicated at B in Fig. 2. Likewise, when the carriage reaches the end of its travel, the pile skews and the part of the pile in the chute takes'the position shown at C in Fig. 2. This skewing of the pile from side, to side is permitted by the outwardly extending portions of the chute 19%. Thus, it

will be seen that, by having the chute 19a closed at the top and sides, the pile 16 of worksheets is held to the table, yet is permitted to move within reasonable limits and is prevented from slipping ofi the paper table. The depth of the chute 19a, that is to say, the distance between the top plate 26 and the portion 25 of the paper table, is sufficient to permit one side of the pile to rise as is natural during the skewing movements of the paper.

This skewing movement of the pile 16 might have very serious and undesirable effects on the part of the pile supported by the platen, for the side thrust on the pile might cause the worksheets to slip on one side or the other on being fed through the platen. This difliculty, however, is avoided by the present invention by the provision of a pair of lateral guides 31 on the intermediate portion 32 of the paper table 19. These guides reach forwardly to a point close to the end 22 of the paper table at the introductory side of the platen and at this point are arranged to provide between them a space just sufficient for the pile of worksheets to move freely. Thus, the guides 31 accurately control the pile as it approaches the platen. Instead of extending rearwardly in a straight line, in which event the entire skewing movement would need to be accommodated for in the chute 19a, with the result that the movement of the paper or the travel of the carriage might -be impeded, the lateral guides 31 of the present invention are so shaped and formed as to diverge outwardly as they extend rearward- 1y, so that the space between them increases toward the rear. The amount of rearward flaring provided is in excess of that required when the guides are mounted as shown in Fig. 2, but, so that they will operate efiiciently under all conditions, the lateral guides are 4 curved toward the side plates 28 of the chute.

In order that the pile of worksheets may be brought to the desired place laterally on the platen 12 and that worksheets of different widths may be used, the lateral guides 31 are 'mounted for adjustable movement on the intermediate portion 32 of the paper table. For this purpose, the lateral guides are each provided with a pair of posts 33 passing through slots 34: in the paper table and having locking nuts 85 located thereon on the underside of the paper table 19. \Vhen it is desired to adjust the lateral guides. the knurled heads 36 of the posts 33 are turned to loosen the posts and the lateral guide is slid bodily across the paper table 19 to the proper position, which operation is permitted by the slots 34. After this iswlone, the posts are again tightened and the lateral guide is securely held in adjusted position. I

It will be seen from the foregoing, that the pile of worksheets after passing through the chute 190, the top plate 26 and the side plates 28 of which confine the pile to the paper table at the rear portion 25 thereof, pass forwardly over the intermediate portion 32 where the pile is engaged by the lateral guides 31 which travel of the carriage with relation to thenon-traveling supply 18 of worksheets.

In orderto prevent the guide margin of the pile 16 from slipping up and over the lateral guides 31, the latter are provided with overhanging plates 37 to engage the margins of the pile. At their rear ends, the overhanging marginal plates 37 are'curved upwardly at 38 so that the sheets of the pile readily pass beneath them.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others.

Having thus described the invention, what is claimed as new and for which it is desired to obtain Letters Patent, is

- 1-. In a typewriting machine, the combination of a traveling carriage; a platen mounted in said carriage; and a paper table mounted in said carriage and having a relatively exten sive curvilinear surface reaching from the introductory side of the platen rearwardly and downwardly to a point behind the rear of the frame of the machine, the rear portion of the table having side edges converging as they extend forwardly and a cover portion to hold the pile of worksheets against removal from the table except by longitudinal movement of the worksheet, and the forward portion of the table having guides converging as they extend forwardly for engaging the side edges of the pile and bringing the pile to a predetermined position lateraly relative to the platen, the said guides being adjustable on the table to vary the point of introduction of the pile of worksheets to the platen and to accommodate worksheets of different widths.
